Answer:
A) convex and regular
Step-by-step explanation:
The polygon has all equal sides so it's regular ; 8 equal sides so it's a regular octagon.
An octagon has no angles pointing inwards so it's convex

convex and regular
Answer:
Step-by-step explanation:
solution:
given:- BE is bisector of ∠DBC and BE//AC
statement reasons
1. ∠DBE= ∠BEC 1. since, BE is bisector of ∠DBC
2.∠DBE=∠BAC 2. corresponding angle are equal
are equal.
3.∠EBC=∠BCA 3. alternative angle are equal
4.∠BAC=∠BCA 4. from statement 1,2,3
5 therefore, triangle ABC is 5. if base angle are equal it is a an isosceles triangle isosceles triangle
6. AB=BC 6.corresponding sides of equal angle
isosceles triangle are equal
proved
Answer:
There are 52 cards in a deck. Four kings and 13 clubs. So the probability of choosing a king or a club is 17/52. The probability that it's both a king and a club is 1/52 because it's only one king that's a club. Hence for drawing a card from a deck, each outcome has probability 1/52. The probability of an event is the sum of the probabilities of the outcomes in the event, hence the probability of drawing a spade is 13/52 = 1/4, and the probability of drawing a king is 4/52 = 1/13.
